Abstract:



This study assesses the level of natural radioactivity due to radionuclides, 226Ra, 232Th and 40K, in 28 tap water samples collected from 6 most populated townships of Abidjan by using gamma spectrometry method for analysis. The activity concentrations of 226Ra, 232Th and 40K varied from < AMD to 0.82 Bq/L, < AMD to 0.73 Bq/L and 0.82 to 5.91 Bq/L, respectively, with mean values of 0.36±0.06 Bq/L, 0.11±0.04 Bq/L and 2.08±0.69 Bq/L respectively, measured from all the water samples studied. The annual effective doses due to the ingestion of the natural radionuclides measured in the samples ranged from 8.06 to 127.41 &muSv/y with an average value of 39.62±11.62 &muSv/y. This average calculated annual effective dose was found to be much lower than the guideline doses of 100 &muSv/y and 290 &muSv/y respectively recommended by WHO and UNSCEAR. Therefore no harmful effect is expected directly to the population by drinking this water.
